As page sizes increase, we also need to deal with subpage uareas.
Why? Is it really worth recovering the rest of the page containing
uarea? While there certainly are machines so small that that much
memory is worth thinking about, I'm inclined to doubt that that occurs
together with pages big enough that a subpage uarea is an issue.
Well, mips can now have 16KB pages and USPACE used to be 8KB so I can
put two uareas per page now. And I can see going to 32KB or 64KB
pages if you have 16+GB of ram. The situation is closer than you think.
